All right, today we're going to use technology to do some matrix calculations and so the first thing you have to do is to be able to enter your matrices into the ti so you need to find the matrix menu which you hit by the second function in matrix enter in your and you see the screen on the left.
00:20
We want to go to the edit to enter in our matrices and so once you choose edit and choose select matrix a with that's matrix you're going to enter then you type in the dimension and which will be the rows by the columns, hit enter each time.
00:36
After you have to enter, it will take you to the first row, first column.
00:39
You type in your entry, hit enter, and then it will take you to the first row second column.
00:44
So after you've entered your matrix c's, in this problem we're going to need both a and c.
00:50
So you'll repeat this process for c.
00:53
And then we'll notice that we need to find the transpose of the matrix a.
00:59
So to find the transpose, what we're going to do is, first thing is you're going to need to have matrix a appear on your screen...
